A float fitted with a magnet slides along a guide tube and follows
variations of fluid level. The float unit consist of a magnet-carrying
float mounted around a stainless steel tube.
As the float passes up or
down the tube, a reed switch chain is actuated inside the guide tube. Reed
switches is act as a variable resistance. The variable resistance
signal is coverted into an analog 4-20mA signal by a 2 wires transducer
. The current output is proportional to the liquid l level in the tank.
The transducer is mounted in a standard or flam-proof atex housing
outside of the tank. The IS version is also available.
